Static Files	/static/	/backend/static/	✅ Mapped
Media Files	/media/	/shared/media/	✅ Mapped
Scripts	/scripts/	/scripts/	✅ Preserved
Dependencies	/pyproject.toml	/backend/pyproject.toml	✅ Mapped

Import Path Updates Required ✅

Django Settings Updates:

# OLD
INSTALLED_APPS = [
    'accounts',
    'parks',
    'rides',
    # ...
]

# NEW
INSTALLED_APPS = [
    'apps.accounts',
    'apps.parks', 
    'apps.rides',
    # ...
]

Media Path Updates:

# NEW
MEDIA_ROOT = BASE_DIR.parent / 'shared' / 'media'

Development Workflow Validation

Package Management ✅

Backend (UV):

• ✅ uv add <package> for new dependencies
• ✅ uv run manage.py <command> for Django commands
• ✅ uv sync for dependency installation

Frontend (pnpm):

• ✅ pnpm add <package> for new dependencies
• ✅ pnpm install for dependency installation
• ✅ pnpm run dev for development server

Root Workspace:

• ✅ pnpm run dev starts both servers concurrently
• ✅ Individual server commands available
• ✅ Build and test scripts coordinated

Development Scripts ✅

# Root level coordination
pnpm run dev              # Both servers
pnpm run backend:dev      # Django only
pnpm run frontend:dev     # Vue.js only
pnpm run build           # Production build
pnpm run test            # All tests
pnpm run lint            # All linting
pnpm run format          # Code formatting

Deployment Strategy Validation

Container Strategy ✅

Multi-container Approach:

• ✅ Separate containers for backend and frontend
• ✅ Shared volumes for media files
• ✅ Database and Redis containers
• ✅ Nginx reverse proxy configuration

Risk Assessment and Mitigation

Low Risk Items ✅

• File organization: Clear mapping and systematic approach
• Package management: Both UV and pnpm are stable and well-supported
• Development workflow: Incremental changes to existing process

Medium Risk Items ⚠️

• Import path updates: Requires careful testing of all Django apps
• Static file handling: Need to verify Django admin continues working
• API integration: New frontend-backend communication layer

Mitigation Strategies:

• Comprehensive testing suite for Django apps after migration
• Static file serving verification in development and production
• API endpoint testing and documentation
• Gradual migration approach with rollback capabilities

High Risk Items 🔴

• Data migration: Database changes during restructuring
• Production deployment: New deployment process requires validation

Mitigation Strategies:

• Database backup before any structural changes
• Staging environment testing before production deployment
• Blue-green deployment strategy for zero-downtime migration
• Monitoring and alerting for post-migration issues
